Graph the equations below accurately. Find the point of intersection of the two lines. You will type your x value in the first part and the y value in the second part of the question. If the answer if no solution then type NS in both parts and if the the answer is infinite solutions then type I in both parts.

Question

y = 5x - 7

y = 6x +2

What is the x value?

Answer 1

well right off you see where they cross
5x-7 = 6x+2
so
-9 = 1 x so x is -9 at the intersection
then at that intersection
y = 6x+2 = -54 + 2 = -52

You can check that with the other equation
y = 5x-7 = -45 - 7 = -52 sure enough

Answer 2

wait so the x value is ____
